The sum of two numbers is 23. The difference of the numbers is 7.4. What are the two numbers?

Brums [2.3K]

X+y=23
X-y=7.4

X+y=23
y=23-X

X-y=7.4
(23-y)-y=7.4
23-2y=7.4
-2y=-15.6
Y=7.8

X+y=23
X+7.8=23
X=15.2

Therefore the two numbers are 7.8 & 15.2

(PLEASE HELP ME) !!! (picture is shown!) Plane W and Plane J intersect at which of the following?

fredd [130]

Answer:

it looks like it intersects at line t.

Step-by-step explanation:

I mean, just look at the picture. where does plane W and plane J touch? its not line p because that line is intersecting plane W and plane B, its not line a because that's intersecting planes V and J, and then its not B because they obviously do intersect.

I hope this helps you out and have a wonderful day!

Suppose you know that ∠s and ∠y are complementary, and that m∠s = 4(m∠y) − 110°. find m∠y. solution

Paul [167]

∠s + ∠y are complementary
∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90
4y - 100 + y = 90
5y = 90 + 100
5y = 190
y = 38

Ans: y = 38°
